摘要：The inhomogeneous Navier-Stokes system serves as a fundamental model for describing the evolution of multi-phase flows, comprising several immiscible, incompressible fluids with distinct densities. The mathematical analysis of this system becomes significantly more challenging when the density is merely bounded. In this talk, we introduce recent progress in this area, focusing on three main aspects: the uniqueness of Lions’ weak solutions; the global existence and uniqueness of Fujita-Kato solutions; the density patch problem.
